Cold Brew Coffee Filter Cartridge is used for steeping coarse coffee grounds in cold water for 12–24 hours inside a removable fine-mesh cylinder. FDA 21 CFR is the reference cited for it on drawings, datasheets and purchase orders.

The dimensions in the table below are supplied to suit FDA 21 CFR. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
